Electrochemical Behavior of Electroactive PVS/PANI Films Containing Chemically Modified Cellulose

Article Preview

Abstract:

Electroactive films containing cellulose modified with cationic and anionic groups were prepared with polyaniline (PANI) and poly (vinyl sulfonic acid) (PVS). The modifications were performed with (aminomethyl) pyridine (AMP), ethylenediamine (EDA), buthylenediamine (BN), bis-(aminopropyl) piperazine (APP), maleic anhydride (MA), and phosphate PO43- groups. The films were prepared using the layer-by-layer (LbL) technique, utilizing dispersed cellulose in a PANI solution forming the PVS/PANI system (cationic or anionic cellulose). Films of unmodified microcrystalline cellulose (MC) were also prepared for comparison. The films were characterized by cyclic voltammetry. The electrochemical responses of PANI present in the film, especially in terms of current density and redox potential, were found to be influenced by the modification of the cellulose.
